Our climate is changing. And while the increase in extreme weather we have experienced in New York City and around the world may or may not be the result of it, the risk that it might be – given this week’s devastation – should compel all elected leaders to take immediate action.

…

But we can’t do it alone. We need leadership from the White House – and over the past four years, President Barack Obama has taken major steps to reduce our carbon consumption, including setting higher fuel-efficiency standards for cars and trucks. His administration also has adopted tighter controls on mercury emissions, which will help to close the dirtiest coal power plants (an effort I have supported through my philanthropy), which are estimated to kill 13,000 Americans a year.

Voters, you have a major decision to make. Who’s the right man for the job?

One sees climate change as an urgent problem that threatens our planet; one does not. I want our president to place scientific evidence and risk management above electoral politics.

Perhaps Mayor Bloomberg could start by managing the risk in his own city.
